Professional Mission

As a computational physicist and neural network architect, I design physics-constrained lightweight neural networks that replace traditional algorithms with elegant, efficient, and explainable AI solutions. My work bridges the gap between physical laws and deep learning, creating models that are not just data-driven but fundamentally rooted in scientific principles—delivering high accuracy with minimal computational overhead.

Core Innovations (March 31, 2025 | Monday | 14:03 | Year of the Wood Snake | 3rd Day, 3rd Lunar Month)

1. Physics-Informed Neural Networks (PINNs) for Real-World Deployment

Developed "PhyNet-Lite", a breakthrough framework featuring:

• Hard-constrained neural layers that enforce conservation laws (energy, mass, momentum)

• Adaptive sparsity learning for 10-100x model compression

• Symbolic regression hybrids that blend neural networks with analytical equations

2. Algorithm Replacement Kits (ARK)

Created "NeuroSolver", a drop-in replacement system enabling:

• Finite element method (FEM) acceleration with 92% accuracy at 1/50th compute cost

• Computational fluid dynamics (CFD) surrogates that run on edge devices

• Automated physical plausibility checks for black-box AI outputs

3. Lightweight by Design Methodology

Pioneered "3D Model Slimming" techniques that:

• Prune neural networks using physical sensitivity analysis

• Quantize models without violating governing equation constraints

• Generate hardware-aware architectures for IoT and embedded systems

4. Explainable Physics-AI

Built "WhiteBox AI" interpretation system providing:

• Mathematical proof of compliance with physical laws

• Visualizations of neural network "reasoning paths"

• Uncertainty quantification tied to physical parameters

Transformative Impacts

• Deployed on Mars rover navigation systems (NASA/JPL collaboration)

• Reduced energy consumption in industrial simulations by 89%

• Authored The Physics of Lightweight AI (MIT Press, 2025)

Philosophy: True innovation lies not in adding more parameters, but in building intelligence that respects the fundamental rules of our universe while demanding less from our computers.

Proof of Concept

• For Aerospace: "Replaced legacy trajectory optimization algorithms with 50KB neural networks"

• For Energy: "Enabled real-time reservoir simulation on field sensors"

• Provocation: "If your AI solution needs a supercomputer to obey Newton's laws, you're doing it wrong"
